Solution Overview

Problem

Existing anatomical mapping techniques lack the ability to efficiently indicate unmapped regions and assess the quality of the mapping in real-time, leading to incomplete and potentially inaccurate medical procedures.

Innovation Solution

A system and method that utilizes a processor to compute an estimated anatomical surface, display unmapped regions, and evaluate mapping quality by defining a 3D shell to provide real-time feedback on mapping completeness and accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional anatomical mapping techniques are used, then mapping data can be collected, but unmapped regions cannot be efficiently identified and mapping quality cannot be assessed in real-time

Engineering Contradiction:
Improveunmapped regions informationVSAvoidmapping system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent introduces a 3D shell structure that extends into the body cavity from the anatomical surface, adding a spatial dimension for visualizing unmapped regions. This 3D visualization layer allows physicians to see gaps in coverage without adding physical complexity to the mapping apparatus itself.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The processor acts as an intermediary that receives mapping data from the catheter, computes the 3D shell, identifies unmapped regions, and presents this information to the physician. This intermediary processing layer handles the complexity of real-time analysis without requiring the physician to directly manage complex algorithms.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If comprehensive anatomical mapping is performed to ensure complete coverage, then mapping accuracy improves, but procedure time increases

Engineering Contradiction:
Improvemapping completenessVSAvoidprocedure time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system provides real-time feedback by continuously updating the 3D shell visualization to show unmapped regions as the catheter moves. This immediate feedback allows the physician to adjust the mapping path dynamically, ensuring complete coverage while avoiding redundant measurements in already-mapped areas.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system pre-computes the 3D shell structure and potential unmapped regions before the physician begins detailed mapping. This preliminary visualization guides the physician's initial catheter positioning, preventing time-wasting gaps in coverage during the actual mapping procedure.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If real-time mapping quality assessment is implemented, then mapping reliability improves, but computational requirements and system complexity increase

Engineering Contradiction:
Improvemapping quality assuranceVSAvoidprocessing system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex computational tasks of 3D shell computation and unmapped region identification from the real-time processing requirement. By separating the computational heavy lifting into background processing that updates the visualization, the system maintains reliability without requiring the entire system to be complex in real-time operation.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A method includes receiving an anatomical mapping that includes multiple measurements acquired at multiple respective locations within an organ of a patient. An estimated surface of the organ is computed based on the measurements. A three-dimensional (3D) shell of the organ, which extends inwards from the estimated surface of the organ and has a predefined thickness, is defined. A quality of the anatomical mapping is estimated based on the measurements whose locations fall within the 3D shell.
